Lishi 2-in-1 SC1 lockpick is designed to unlock only Schlage SC1 keyholes. The SC1 cylinder can also be found in the Sparrows Revolver!

This tool from Mr. Li is a 2-in-1 lockpick. This means that you can not only unlock Schlage’s SC1 locks harmlessly, but also decode them. Decoding the lock means that you can read exactly how to make a custom key for the lock that has been opened.

During lockpicking you can read the depths of each notch This allows you to make a new key for the SC1 lock afterwards using the decoder
